Controllers Procurement Notes

Verify the specific suffix codes to confirm the exact package type and temperature rating before procurement. Ensure compatibility with the host system's power delivery requirements, specifically the 1.05 V and 3.3 V rails. Confirm that the design accommodates the required 24 MHz crystal oscillator input. Check moisture sensitivity levels and storage conditions to prevent damage prior to assembly. Validate that the selected variant matches the intended application environment constraints.

Controllers Selection Notes

Select this component when a dual-port USB 3.0 solution is required for compact form factors. Consider the 56-pin QFN package for space-constrained designs on motherboards or expansion cards. Evaluate the thermal performance within the specified -40°C to +70°C range for the target environment. Compare against single-port or four-port alternatives if port count requirements differ. Ensure the host processor supports the necessary interface protocols for hub communication.

Controllers Part Context

This part belongs to the µPD720211 series of USB hub controllers from Renesas Electronics. It complements other variants like the UPD720201 host controller, forming complete USB 3.0 ecosystem solutions. The series emphasizes low power consumption and high data throughput efficiency. It serves as a critical interface bridge between host systems and peripheral devices in modern electronics.

Controllers Replacement Considerations

Direct substitutes include the UPD720211K8-711-BAL-M1-A variant, which shares similar functional characteristics but may differ in packaging or manufacturing details. Verify pin-to-pin compatibility and electrical specifications before swapping. Consult official Renesas documentation for any updated revisions or recommended alternative parts within the same product family.
